Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.
Players take turns adding shapes made of three squares to a grid. They try to fit their shapes on the grid in a way that blocks the other player.
In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.
In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.
In this activity, learners explore their eye pupils and how they change.
In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.
In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.
Like water drops in falling rain, a CD separates white light into all the colors that make it up.
Learners demonstrate how water can distort, refract and magnify light.
In this activity, learners explore how nanosized structures can create brilliant color.
In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
In this activity, learners create a cylindrical mirror to see themselves as others see them.
This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.
In this activity about light and perception, learners create pictures in thin air.
In this activity, learners add squares to paper dominoes to make polyominoes.
In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.
In this activity, learners explore the invisible infrared radiation from an electric heater.
